Biotin, also known as vitamin B7 and vitamin H, is one of the lesser known vitamins of the B complex group. It is one of the most active biological substances, since it has some effect on bacteria and yeast. Its effect is like that of egg white. Biotin is insoluble in fat solvents and easily soluble in hot water. Factors that can destroy this vitamin are oestrogen, sulpha drugs, water, certain food processing methods, alcohol and egg white. Frequent use of antibiotics can hinder the synthesis of the vitamin.
